  As shown in FIGS. 3A and 3B, the locking portion 23 includes the cover body side edges 20 a of the cover body main body 21 that are on both sides of the storage portion 22 in the short direction Y of the cover body 20. 22 is formed in a direction opposite to the concave direction, that is, folded back to the back side of the cover body 20.

  The folding amount of the locking portion 23, that is, the locking portion width W1 in the short side direction Y is a length corresponding to both side edges of the housing portion 22 from the cover body side edge 20a of the cover body 20, that is, a frame-shaped cover body main body. 21 is set to a length corresponding to the side width of the long side portion. Further, the folded height H of the locking portion 23 (see FIG. 3B), that is, the interval formed between the cover body 21 and the locking portion 23 is determined by the locking portion 23 being locked. The thickness of the base material 30 is set to be about the thickness of the base material 30 that can hold the locking portion 31.

  In addition, since the latching | locking part 23 aims at latching with the to-be-latched part 31, the latching | locking part width W1 and the folding | turning height H are accommodated in the thickness of the base material 30, or the accommodating part 22, for example. It can be set appropriately according to the weight of the packaging object.

The locking portion 23 has a substantially parallelogram shape in front view in which the inner side in the lateral direction Y protrudes downward, and a stopper piece 24 is configured by a portion protruding downward of the locking portion 23. The length of the stopper piece 24, that is, the downward projecting amount, is an amount that allows the base member 30 to be locked with the stopper portion 32. Therefore, the length from the locking portion upper end 23 a of the locking portion 23 to the lower end of the stopper piece 24 is set as a locking portion length L 1 of the locking portion 23 including the stopper piece 24.
Furthermore, the angle of the upper end of the locking portion 23 is an angle that allows the cover body 20 and the base material 30 to easily start sliding. In the present embodiment, the angle is set to approximately 35 degrees with respect to the longitudinal direction X. Yes.

  The base material 30 constituting the packaging container 10 together with the cover body 20 described above is made of cardboard having a vertically long rectangular shape in front view, which can be appropriately printed on the surface, and further has appropriate shape retention and flexibility. In the surface of the base material 30, as shown in FIG. 3 (c), an L-shaped slit 40 is provided, and the locked portion 31 and the stopper portion 32 are formed by the L-shaped slit 40. Yes. An insertion hole 33 that allows insertion of a display hook (not shown) is provided at the center of the upper portion of the base material 30 in the short direction Y. Further, the vertically long rectangular shape of the base material 30 in the front view is a large shape that is substantially similar to the external shape of the cover body 20 in the front view in the vertically long rectangular frame shape.

  The L-shaped slits 40 are set in a symmetrical arrangement of the base material 30, and each L-shaped slit 40 has a main slit portion 41 parallel to the longitudinal direction X, and a lower end of the main slit portion 41 facing the inner side in the short direction Y. The sub slit portion 42 forms an L shape in front view, and a tear preventing slit portion 43 is formed at the upper end of the main slit portion 41.

  Since the latched portion 31 is provided inside the main slit portion 41 in the short direction Y, the slit interval W4 between the main slit portions 41 in the short direction Y is the lock between the catch portions 23 in the short direction Y. This corresponds to the interval W3. The slit length L2 in the longitudinal direction X is set slightly longer than the locking portion length L1 in order to allow the locking portion 23. In the present embodiment, the main slit portion 41 is arranged at the center of the base material 30 in the longitudinal direction X.

  The outer side of the sub slit portion 42 in the escape direction X <b> 2 constitutes a stopper portion 32 that allows the stopper piece 24 to be locked. Further, since the sub slit portion 42 allows the locking portion 23 to slide, the slit width W2 of the sub slit portion 42 is slightly longer than the locking portion width W1.

  The tear prevention slit portion 43 is formed in an arc shape from the upper end of the main slit portion 41 to the inner side in the short direction Y, and when the cover body 20 and the base material 30 are mounted, the locking portion 23 is connected to the locked portion 31. It is configured to prevent the base material 30 from being damaged by concentrated stress at the upper end of the main slit portion 41 generated by abutment or concentrated stress at the upper end of the main slit portion 41 generated when the base material 30 is bent. doing.

A method of assembling the packaging container 10 by mounting the cover body 20 and the base material 30 thus configured will be described with reference to FIGS.
First, as shown in FIG. 4, the base material side edges 30a of the base material 30 are bent in the short direction Y, and the locking portion 23 and the sub slit portion 42 are made to correspond to each other. The stop 31 is locked and slid in the longitudinal direction X. In the present embodiment, the state in which the locking portion 23 and the locked portion 31 slide while being locked is referred to as slide locking.

As shown in FIG. 5 (a), which shows the state of the sliding engagement between the locking portion 23 and the locked portion 31, the locking portion 23 is slid and locked to the locked portion 31, and the upper end of the locking portion is shown. The slide locking is performed until 23a abuts against the tear prevention slit portion 43 of the main slit portion 41 (a state where the slide locking is completed).
In addition, as shown in FIG. 5B illustrating the state where the sliding engagement between the cover body 20 and the base material 30 is completed, in this state, the stopper piece 24 is not locked to the stopper portion 32, that is, The state where the cover body 20 is locked to the base material 30 is not fixed.

  Therefore, as shown in FIG. 5C illustrating the state where the stopper piece 24 and the stopper portion 32 are completely locked, the cover body 20 is slid in the escape direction X2 with respect to the base material 30, and the stopper piece 24 is moved. By locking to the stopper portion 32, the locking state between the cover body 20 and the base material 30 is fixed by the reaction force of the cover body 20 and the base material 30 or the deflection of the cover body 20 or the base material 30. Can do.

  The packaging container 10 assembled by the mounting method described above can wrap the packaging object by assembling the cover body 20 and the base material 30 by the above-mentioned method after accommodating the packaging object not shown in the housing part 22. it can. In this packaging state, the hooks provided in the merchandise display shelf can be inserted into the insertion holes 33 formed in the base material 30 for display.

  As described above, the packaging container 10 configured by assembling the cover body 20 and the base material 30 is provided with a housing portion 22 that allows the packaging object to be housed in at least one of the cover body 20 and the base material 30. The cover body 20 is provided with locking portions 23 that can be locked to the base material 30 on both sides of the housing portion 22, and allows the base material 30 to be slidably locked in the longitudinal direction X. The locked portion 31 is provided at an intermediate position in the short direction Y with respect to the longitudinal direction X of the base material 30, and the locking portion interval W3 and the slit interval W4 are made to correspond to each other and the locked portion 31 starts to be locked. The sub-slit portion 42 that allows the locking portion 23 to slide in the longitudinal direction X with respect to the locked portion 31 is provided at the position, and the cover body 20 and the base material 30 have appropriate shape retention and flexibility. Therefore, the outer shape of the cover body 20 and the base material 30 Jo, and size to without corresponding to each other, can be configured to rich design due to the shape.

  Specifically, the cover body 20 includes locking portions 23 that can be locked to the base material 30 on both sides of the accommodating portion 22, and allows the base material 30 to be slidably locked in the longitudinal direction X. Since the to-be-latched portion 31 is provided at an intermediate position in the short direction Y with respect to the longitudinal direction X of the base material 30, the cover body 20 is locked to the base material side edges 30 a of the base material 30. There is no need to make the outer shape and size of the cover body 20 and the base material 30 correspond to each other.

  Therefore, since the part which the base material 30 exposes in the transversal direction Y outer side of the cover body 20 can be formed, for example, by making the exposed base material 30 part of the four sides with respect to the cover body 20 into a uniform pattern The packaging container 10 with high designability can be configured.

  Further, for example, even when the cover body 20 has the same shape as that used in the packaging container 10 described above, the base material 30 having various shapes such as a heart shape as viewed from the front is formed as shown in FIG. Thus, the packaging container 10 with high design can be configured.

  Moreover, even if the cover body 20 has the same shape as that used in the packaging container 10 described above, a plurality of L-shaped slits 40 can be formed on the base material 30 having an appropriate design as shown in FIG. May be formed. Furthermore, by forming the plurality of L-shaped slits 40 in the base material 30 at appropriate positions and orientations without being trapped in the longitudinal direction X and the lateral direction Y, the packaging container 10 with higher design can be obtained. It can also be configured.

  Thus, if the position and orientation of the cover body 20 with respect to the base material 30 are within the plane of the base material 30, the restriction is eliminated, thereby increasing the degree of freedom in design of the packaging container 10, and the packaging container 10. The overall design can be improved, and for example, consumers' willingness to purchase can be improved.

  Further, since the cover body 20 is not locked to the base material both side edges 30a of the base material 30, and it is not necessary to make the outer shape and size of the cover body 20 and the base material 30 correspond to each other. 22 can be formed in a shape corresponding to the shape of the object to be packaged, or the cover body 20 can be formed smaller than the base material 30, and the amount of the resin constituting the cover body 20 can be reduced.

  Further, the slit interval W4 that is the interval between the locked portions 31 corresponding to the lock portion interval W3 that is the interval between the lock portions 23 is the interval between the lock start positions in the mounting direction X1 in the longitudinal direction X. The cover body 20 can be smoothly mounted on the base material 30 by setting so as to have the above intervals.

Specifically, the cover body 20 is locked to the base material 30 at the locking start position and smoothly mounted by associating the locking portion interval W3 and the slit interval W4 at the locking start position. Can do.
Furthermore, in the mounting direction X1, by setting the slit interval W4 to be equal to or greater than the interval of the locking start position, the assembling work from the locking start position to the mounting completion position can be facilitated, and smooth sliding becomes possible.

  In addition, the cover body 20 includes a stopper piece 24 that allows locking with the base material 30 in the escape direction X2 opposite to the mounting direction X1, and the base material 30 has a stoppered portion 32 corresponding to the stopper piece 24. The length of the to-be-latched part 31 in the longitudinal direction X is longer than the latching part length L1, so that the cover body can be secured without being fixed by a tape or a seal as in the prior art or bonded by glue or the like. The assembled state of 20 and the base material 30 can be maintained, and it can be used repeatedly by releasing the locking of the stopper piece 24 and the stopper portion 32.

  Specifically, by locking the stopper piece 24 to the stopper portion 32, the assembled state of the cover body 20 and the base material 30 can be fixed without being fixed by tape or a seal, or bonded by glue, The cover object 20 and the base material 30 can hold the packaging object in the accommodating portion 22.

Further, when the insertion hole 33 is displayed using a hook, the weight of the packaged object accommodated in the accommodating portion 22 and the weight of the cover body 20 act downward, so that the stopper piece 24 and the stopper portion 32 are locked. The packaging object can be reliably held in the housing portion 22 without being inadvertently removed.
Furthermore, since the cover body 20 has appropriate flexibility, the stopper portion 24 locked to the stopper portion 32 sandwiches the stopper portion 32 between the cover body main body 21 and is thus in the locked state. Can be securely held.

  As described above, since no tape or glue is used, the number of machines or processes required for fixing and bonding is improved, so that safety in the factory is improved, costs are reduced, and the cover body 20 and the base material 30 are repeatedly detached. Is possible.

  Moreover, the breakage in the locked portion 31 of the base material 30 is provided by providing the tear prevention slit portion 43 that prevents the base material 30 from tearing at the tip portion of the mounting direction X1 in the longitudinal direction X of the locked portion 31. Can be prevented in advance.

  Specifically, the slits 43 reduce the concentrated stress on the locked portion 31 generated when the locking portion upper end 23a hits the end of the locked portion 31 or when the base material 30 is bent. By doing or withstanding, damage to the base material 30 can be prevented in advance.

  Therefore, the durability of the base material 30 is improved, and the packaging container 10 has a concentrated stress on the locked portion 31 generated by the work when the cover body 20 and the base material 30 are assembled or vibration after the assembly. Thus, defective articles due to breakage of the base material 30 can be reduced.

  Furthermore, even if the cover body 20 has the same shape as that used in the packaging container 10 described above, as shown in FIG. By configuring the viewing-side concave shape, the three-dimensional base material 30 can be configured. That is, since it is not necessary for the outer shape of the base material 30 to correspond to the shape of the cover body 20, a new function can be added to the planar base material 30 so far. Further, as shown in FIG. 8B, both side edges 35 of the outer portion 34 may be formed in an arc shape.

  In the above description, the substantially planar substrate 30 is used. However, for example, an L-shaped slit 40 may be provided in a substantially planar portion of a part of a box or a cylindrical body to be used as a substrate. Good. Thus, for example, when the L-shaped slit 40 is provided in a part of the flat portion of the box and used as the base material, the cover body 20 in which the packaging object is accommodated in the accommodating portion 22 inside the box. The locking portion 23 is locked to the L-shaped slit 40 and assembled. And it conveys in that state, after conveyance, the latching of the latching part 23 with respect to the L-shaped slit 40 is cancelled | released, the cover body 20 is taken out with the packaging target object, it reassembles on the outer side of a box, and product display can do. By doing in this way, while using a box as a case at the time of conveyance, while preventing breakage at the time of conveyance, it can be used as a base material in the case of product display.

  The main slit portion 41 includes a main slit portion 41 parallel to the longitudinal direction X, a main slit portion 41 in a direction intersecting the longitudinal direction X, or a main slit portion 41 that is not only linear but slightly curved. The interval may be constant or simply increased with respect to the interval between the main slit portions 41 at the combination and locking start position, or a combination thereof. The sub-slit part 42 can be set from the end of the main slit part 41 in the escape direction X1 to the outside in the short side direction Y, and the sub-slit part 41 and the locking part 23 can be made to correspond to each other. The L-shaped slit 40 can also be formed in a U shape by connecting.
